Impact of Seed Treatment with Tree Leaf Extracts on Physiological Parameters of Radish

Lab experiment was conducted with an objective of studying the influence of tree leaf extracts of selected trees on seed attributes and identifying the best leaf extract that ensure high quality seeds in radish. The experiment was carried out from September 2013 to January 2014 in a completely randomized design replicated thrice. The experiment consisted of 7 treatments i.e. different green tree leaf extracts @ 5% inthe form of seed treatment and control using distilled water. The results indicated that there were significant differences in seed attributes due to the application of tree leaf extracts. Seed quality parameters were foundto be high in seeds treated with Jatropha curcas in radish followed by T4 (Annona squamosa) gave higher mean values for all the parameters studied in radish. Hence, it is recommended that seed treatment with T5 fresh leaf extract of Jatropha curcas can be exploited to get good quality seeds/seedlings of vegetables. If Jatropha curcas leaf extract is not available leaf extract of Annona squamosa and Morinda tinctoria may be given as seed treatment.
